UNITED STATES CHARLES LEWIS PATENT OFFICE.

WAGANDT, OF BALTIMORE, MARYLAND, ASSIGNOR TO KEEN & I-IAGERTY, OF SAMEPLACE.

STRAINER.

SPECIFICATION forming part of Letters Patent No. 494,355, dated March28, 1893.

Application filed April 23, 1892.

To aZZ whom it may concern:

Be it known that 1, CHARLES LEWIS WAG- ANDT, a citizen of the UnitedStates, residing at Baltimore city, in the State of Maryland, haveinvented certain new and useful Improvements in Strainers; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable, others skilled in the art to which itappertains to make and use the same.

It is the object of my invention to provide a strainer for milk, or forother purposes, comprising a vessel or rim and a wire cloth or gauzesecured therein.

It is especially the design of my improvement to obviate the necessityfor the use of solder, and do away with the expense and imperfect finishattending that mode of construction.

When the strainer is manufactured according to my invention considerabletime and expense are saved and a very superior article produced ofperfect construction and highly finished appearance.

With such objects in view my invention consists in the parts andcombinations thereof, hereinafter particularly set forth and claimed.

In order to make myinvention more clearly understood I have shown in theaccompanying drawings the manner of carrying the same into practicaleffect, without however intending to limit my invention in its practicalapplication to the particular construction which, for the sake ofillustration, I have set forth.

In said drawings-Figure 1 is a plan view of a strainer, embodying myinvention. Fig. 2 is a sectional view of a portion of the same enlarged,on line IIII, Fig. 1. Fig. 3 is a perspective View, in section, of aportion of the vessel or rim in which the strainer is to be fixed. Fig.4: illustrates the first step in the formation of the retaining ring,showing it as constituting the rim of a circular blank struck up ordrawn into dish shape. Fig. 5 is a perspective view of the ring severedfrom Fig. 6 is aperspective view of the wire cloth or gauze formed tofit said ring and having its edge turned down. Fig. 7 is a sectionalview. of the strainer cloth applied to the ring. Fig. Sis a sectionalview Serial No. 4so,41o. (No model.)

showing the ring and gauze as about to be applied to the-strainervessel.

Referring to the drawings 1 indicates the device in or to which thestrainer is to be socured, in this instance a vessel or basin best seenin Fig. l.

2 is the strainer proper to be attached thereto. It will be understoodthat this strainer may be formed of finely perforated metal or in anyother equivalent manner, but I prefer to employ a fine wire gauze asshown.

3 indicates a malleable ring of suitable material such as tin whichco-operates with the basin or vessel for the securing of the strainercloth in place.

In carrying my inventioninto effect I first form the edge of the vesselaround the aperture at which the strainer is to be attached with aslightly turned edge as shown at 4 in Fig. 3.

I produce the ring 3 in any suitable manner, as for instance by strikingup or drawing a circular disk of tin into the form shown in Fig. 4, andthen severing or cutting out the bottom 7 leaving the ring in the formshown in Fig. 5, having a small lip 5 outwardly turned around one edge.

The strainer cloth is cut into circular pieces and the edges of thelatter turned downin the form of a rim or flange 6 (Fig. 6), and is thenfitted over the ring 3. The ring and gauze are then in the form shown inFig. 7. The gauze and ring are then applied to the vessel in the mannerindicated in Fig. 8, and pressed into the aperture of the vessel so thatthe gauze is firmly clamped between the lip 5 of the ring and the edge 4of the vessel.

At the same operation the lower edge of the ring 3 is turned outwardover said edge 4 to engage the bottom of the vessel and the articlecompleted in the form shown in Figs. 1 and 2. My improved strainer canbe thus finished by and between direct acting dies with great rapidityand at minimum cost, and the use of any seaming machine operating byrotarymotion or by rolling may be entirely dispensed with.

Having thus described my invention, what I claim is- As an improvedarticle of manufacture a strainer consisting of the combination with asuitable vessel or rim having an aperture, of a strainer cloth situatedin said aperture and having a peripheral edge or flange, and a ringhaving an outwardly extending lip situated in the aperture and clampingor confining the said edge of the strainer cloth by said lip, and havingits other or lower edge turned outward to engage said vessel or rim,substantially as set forth. to

In testimony whereof I affix my signature in the presence of twoWitnesses.
